Isotopes are different forms of an element that have the same number of protons but different numbers of neutrons in their nuclei, resulting in different atomic weights. This difference in atomic weight among isotopes is what distinguishes them from a regular element.

Which element has its own isotope and its symbol is D?
The element with its own isotope and the symbol D is deuterium. Deuterium is an isotope of hydrogen with a nucleus containing one proton and one neutron, making it twice the mass of regular hydrogen.
What is an atom called when the number of neutron changes?
An atom with a different number of neutrons is called an isotope of the original element. Isotopes have the same number of protons (and thus the same element) but different numbers of neutrons.
Which is a factor in determining the average atomic mass of an element?
The two main factors in determining the average atomic mass of an element are:the isotopic composition of the element (the fraction of each isotope)the atomic mass of each isotope
What is the average atomic mass of an element is the average atomic masses of what kind of isotopes?
average atomic massof an element=(Atomic mass of first isotope X % of that isotope) + (Atomic mass of second isotope X % of the second isotope)
What is a parent isotope?
These terms apply to the decay of radionuclides. The parent isotope is 'the starting point' of a decay series that when it decays, by giving off radiation, changes into another element, or isotope of the original element (the daughter isotope). For example: When Uranium 238 (parent isotope) decays and gives off an alpha particle, it transmutes into Thorium 234 (the daughter isotope).
Which element has its own isotope and its symbol is D?
The element with its own isotope and the symbol D is deuterium. Deuterium is an isotope of hydrogen with a nucleus containing one proton and one neutron, making it twice the mass of regular hydrogen.
What element or lack of element distinguishes theft from robbery?
INTENT
What is the differences between isotope and element?
Regular elements contain regular neutron number and the same number of protons and neutrons. Isotopes have different neutron numbers than the original element, but the same number of protons and electrons.
Why need to know the percentage of each isotope of an element to determine the atomic mass?
Because each isotope of an element has a mass different from any other isotope of the same element, and the atomic mass of an element is an average, weighted by the proportion of each isotope, in the naturally occurring element.
How are isotops different from regular elements?
Isotopes are atoms of the same element with different numbers of neutrons. Some elements have more than one isotope and some don't. The isotopes of an element are chemically identical, they just differ in mass. There is nothing special about any particular isotope, elements with them are just as 'regular' as the few which don't.
What element has the atomic mass of 22?
An isotope of Neon. This isotope accounts for between a fifth and a quarter of the element.
What best describes a radioisotope?
its nucleus is unstable
An isotope shares the atomic number with its element atom How does it differ from the element atom?
An isotope shares the atomic number with its element atom. How does it differ from the element atom?
What is an atom called when the number of neutron changes?
An atom with a different number of neutrons is called an isotope of the original element. Isotopes have the same number of protons (and thus the same element) but different numbers of neutrons.
What distinguishes the atom of one element from the atom another element?
the number of protons
How do you find the atomic number of an isotope?
The atomic number of an isotope is the same as the element it belongs to. You can find the atomic number of an isotope by identifying the element it is a part of on the periodic table.
An element with a number of neutrons different from its normal number is called a what?
It is called an isotope.
